I made a post about colour schemes a few days ago - I'm just going to copy and paste it:

If there are colour schemes, they should be congruent with the mood of the game. For example if there were a choice of different coloured cloaks, they should all have a dark, dusky colour tone. For example, dark yellow or dark green only, rather than bright green or bright yellow.

I just took the time to actually view the new Thief modell (Dont hurt me! O_O).
And i have to say i absolutely LOVE the hatted thief!
Kind of reminds me of Van Helsing and Dark Watch.
Maybe it would be more awesome if the brim of the hat was a bit bigger (a bit like a cowboy hat, in a dark kind of way.)

Jk awesome. And so intricate. I guess thats the fancy edition for leet players unlocked by 500 crackarrow kills. Normalos just get the old black "Leftovers from when i made my typical ugly thief rat pelt outfit" one.
